A trapezium of sides 10cm and 21cm and height 8cm is inscribed in a circle of radius 7 calculate the area of the region not covered by the trapezium

You know the area of a trapezoid is

(10 + 21) / 2 * 8 = 124 cm^2

The area of the circle is

3.14 * 7^2 = 154 cm^2

The difference is 30 cm^2

your answer would be b

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
